HAWSE-PIPE STOPPER.

SLIPECIPICATEON forming part of Letters Patent No. 346,685, dated August 3, 1886.

Application filed FehrnaryQO, 1886. Serial No. 192,6(15. (No model.)

10 aZZ whom it may concern:

Be it known that I, ELISHA F. ROBBINS, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Hawse-Pipe Stoppers, of which the following is a specification.

This invention has for its object to provide a simple and serviceable stopper for hawse-pipes of vessels, adapted to be held in place by the anchor-chain when the anchor is not in use, and capable of being instantly releasedto free the hawsepipe from obstructions when the anchor is to be dropped.

To these ends the invention consists in the improvements which I will now proceed to describe and claim.

Ot' theaccompanying drawings,forming a part otthis specification, Figure 1 represents a side view of my improved stopper in place on the outer end of the hawse-pipe. Fig. 2 represents a section on line a: (c, Fig. 1. Fig. 3 represents a side view showing also an anxiliary stopper. Fig. 4 represents a side view of a somewhat different construction, and Fig. 5 represents a section on line 3 y, Fig. 4.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents a hawse-pipe, and b a port-ion of the anchor-chain passing through it.

0 represents my improved stopper,which is composed of a plate of sufficient size to cover the outer end of the pipe a, and having at its inner side a marginal rim or flange, c, which surrounds the projecting outer end of the hawse-pipe when the stopper is in place and keeps the stopper from slipping edgewise oft from the pipe.

In the stopper is formed a slot, (1, of suitable size to receive one of the links of the chain I),

the link being inserted edgewise in the slot.

hen the stopper is thus engaged with a chainlink, the adjoininglinks are close to the opposite sides of the stopper and stand crosswise of the slot, so that the stopper cannot move in the direction of the. length of the chain.

The stopper is provided with an eye or eyes for the attachment of a lanyard or lanyards,e, by which the stopper can be lowered from the ships rail to the outer end of the hawse-pipe and engaged with the chain passing therethrough. When the stopper is thus engaged with the chain, thelatter is drawn inwardly by the Windlass until the stopper is pressed firmly against the side of the vessel,and thus held in place by the chain. A plug, 2', may be inserted in the lower end of the slot, as shown in Fig. 3, to prevent the admission of water through the slot below the chain. Said plug is provided with a lanyard, j, passing through an eyebolt, 70, on the side of the vessel and upwardly to the rail, so that the plug may be readily withdrawn when it is desired to remove the stopper and let go the anchor. I prefer to place a sheet of rubber, m, in the slot (2, said sheet normally extending across the slot and being slitted to receive the chain 1). \Vheu the chain is in place in the slot, the rubher fits closely around it, and thus practically prevents the admission of. any water to the hawse-pipe. The rubber sheet is preferably applied to the stopper by being clamped between two plates, as shown in Fig. 5, said plates composing the body of the stopper. It will be seen that this device is simple and cf 75 fective and is capable of being easily applied and removed.

The absence of a positive connection between the stopper and the hawse-pipe and the provision of the lanyard as the means for applying and removing the stopper enable the operation of applying and removing the stopper to be performed from the ships rail, and there is no occasion for the sailor to go down upon the outside of the ship to either apply or remove the stopper. \Vhen it is desired to quickly release the chain, as is often necessary, a pull upon the lanyard is all that is required.

The application of the stopper to the outer end of' the hawse-pipe enables the stopper to be held in place against the hawse-pipe by the chain, the latter being drawn inwardly by the Windlass, as before described.

The slot may extend from the side of the stopper horizontally instead of from the bottom.

The stopper may be applied to the inner end ofthe hawse-pipeinstead of the outer end, and when used at the inner end may serve as a devils-claw, to prevent the chain from slip pling outwardly through the hawse-pipe.

I claim- 1. A hawse-pipe stopper composed of a loose or independent plate formed to cover the outer end of a hawse-pipe, but having no positive attachment thereto, and provided with a slot formed to receive a chain-link and with a supporting device or lanyard whereby it may be applied to and removed from the hawse-pipe, the arrangement being such that the stopper may be held in place against the hawse-pipe by the chain and quickly disengaged by an upward pull on the supporting device, as set forth.

2. A haWse-pipe stopper composed of a loose or independent plate formed to cover the outer end ofahawse-pipe, and provided with a chainreceiving slot formed to inclose the outer end of the hawse-pipe, a marginal flange, and a supporting device or lanyard, as set forth.

3. Ahawse-pipe stopper composed of a plate formed to cover the end of a hawse-pipe, and provided with a chain-receiving slot and a sheet of rubber extending across said slot and having a slit to receive the chain, as set forth.
